Fix the pipeline prepare-resume implementation to correctly
handle multiple continuous events that request resume on
being pre-empted.
Symptoms of the bug being, when having continuous scanning,
and an active peripheral if a directed advertising is
started the peripheral event are not scheduled causing link
supervision timeout.
This is fixed by not having an enqueued resume event
prepared if there is an enqueued new non-resume event in the
pipeline.
